Why do some substances melt instantly from solid to liquid (like water/ice) and other substances gradually transition (like magma, or metals)?

How come there is no transition state in between something like ice and water like how there is between stone and lava. Is there actually some sort of viscous, in-between, water/ice that I just don’t know about?

Imagine LEGO. Each block represents an atom. Say you make LEGO wall brick by brick so that it’s strong. The blocks are each secured to each other making them stronger as a group and the way they’re arranged. Now make that same wall but add gaps and spaces. It still makes a wall but not a strong. Now lay the blocks side by side without snapping them. They make a wall but it could be knocked down no problem. This is like what you described. Some substances have atoms that are together and form a wall (a solid) but only a tiny bit of temperature (or change in energy, getting knocked over) is required to break that wall. While the strong wall represents substances that have strong bonds between atoms so they need a bigger change in temperature (energy) to get broken apart making the state change slower.
